2. The focus adjustment apparatus according to claim 1, wherein the selection unit selects the main subject candidate located at a position nearest to the in-focus position of the focus lens as the main subject in a case where the operation unit is operated.
3. The focus adjustment apparatus according to claim 1, wherein the selection unit reselects the main subject in a case where the operation unit is operated and a focus state of the selected main subject is lower than a focus state set on the basis of a depth of focus of the focus lens.
5. The focus adjustment apparatus according to claim 1, wherein, in a case where the operation unit is not operated and no main subject is fixed, the selection unit determines the main subject based on a predetermined second condition.
7. The focus adjustment apparatus according to claim 6, wherein the first detection unit detects the first area using a third condition which differs between a case where the operation unit is operated and a case where the operation unit is not operated.
8. The focus adjustment apparatus according to claim 7, wherein the third condition includes a size whose smallest limit of an area to be detected as the first area is smaller in a case where the operation unit is operated than in a case where the operation unit is not operated.
9. The focus adjustment apparatus according to claim 7, wherein the third condition includes an area of an image where the first area is to be detected, and the first detection unit detects the first area within the area larger in a case where the operation unit is operated than in a case where the operation unit is not operated.
10. The focus adjustment apparatus according to claim 7, wherein the third condition includes reliability whose lowest limit of the area to be detected as the first area is made lower in a case where the operation unit is operated than in a case where the operation unit is not operated.
11. The focus adjustment apparatus according to claim 6, wherein the first condition is different between in a case where the operation unit is operated and in a case where the operation unit is not operated.
12. The focus adjustment apparatus according to claim 11, wherein, in a case where the operation unit is operated, the detection unit detects one or more subjects included in at least the first area or the second area as the main subject candidates and, in a case where the operation unit is not operated, the detection unit detects one or more subjects included in the first area and one or more subjects which have been detected as the main subject candidates in the past and included in the second area as the main subject candidates.
